STEAM RADIATOR.

SPECIFICATION forming part of Letters Patent No. 552,643, dated January 7, 1896.

Application filed August 2'7, 18%. Serial No. 521,442. (No model.) Patented in Austria April 4, 1894, N0. 880, and in Hungary June 14, 1894,1T0. 605.

To aZZ whom it may concern.-

Be it known that 1, MAX JAENNIGEN, of Modling, near Vienna, Austria, have invented certain new and useful Improvements in Steam-Radiators, (for which I have obtained LettersPatent in Austria under the date of April 4, 189%, No. 880, and in Hungary under the date of June 14:, 1894, No. 605,) of which the following is a specification.

The object of this invention is to provide stoves or heaters especially adapted for subjecting comparatively large quantities of air to a preliminary heating process for the purpose of supplying central heating ventilating or other similar plant with such preliminarilyheated air. I attain this object by means of hollow steam casings or elements illustrated in the accompanying drawings.

Figure 1 shows, in a vertical section taken on the broken line 00 00 w of Fig. 2, one of the steam casings or elements of a stove or heater. Fig. 2 is a horizontal section of same,

taken through a line y y of Fig. 1. Fig. 3 is a vertical section through the line M N, showing two casings placed ide by side. Fig. a shows an elevation of one of my heaters as fitted up in connection with an exhauster for.

heating a one-story structure, and Fig. 5 an elevation of one of my heaters as employed in heating the upper stories of a building without the aid of artificial means for producing proper circulation of air through the heater.

Corresponding letters of reference throughout the different views refer to corresponding parts.

According to this invention a stove or heater consists of hollow steam-casings E, Figs. 1, 2, and 3, having smooth surfaces and with deep recesses or channels D therein, which, when the casings E are arranged in a row, battery,or series, Fig. 3, form anumber of air compartments or chambers L L, through which the air to be heated may be conducted in the direction indicated by arrows2 2 2, either by means of mechanical appliances, such as fans, to draw or force the air, as shown in Fig. 4, or other suitable means, or the circulation of the air may be caused by the natural differences of temperature, as indicated in Fig. 5, the course taken by such air in either case being opposite to the direction in which the steam passes, which in. the present case is indicated by arrows 1 1 1, Fig. 1.

The heating medium to be employed may be low-pressure exhaust-steam or low-pressure boiler-steam. The air escapes from the heaters at their tops or upper parts at Z.

The sectional area of the air-chambers L should be of an extent in accordance with the required quantity of heated air, its temperature and the resultant heating-surface.

Each heater E is adapted to act independently of the remaining heaters or casings E, whatever their number, so that each exercises its own heating-power.

Large-sized heaters may be divided in a longitudinal vertical plane through a line P Q, Fig. 3, they consisting of flanged halves screwed together, the joining-flanges Z7 b b 5 extending all around each heater section, Figs. 1, 2, and 3.

In the arrangement shown in Fig. 4 the cold air passes through a grating A, entering the heater at G, and leaving it to pass through an exhauster P to be forced by the same through the registers W, the arrows 2 2 indicating the course of the air. enter the heater, leaving it at O in condensed form.

In the arrangement shown in Fig. 5 the registers W are placed at such elevations above the heater that, owing to the chimney-like effect thus produced in the fines leading ,to the same, artificial means for forcing the heated air upward can be dispensed with.

B represents the boiler furnishing the steam, and V V are ventilators in the walls of the building for producing proper circulation of the air.

By employing a curved or arched cross connection between the upper ends of the two branches of my stoves or heaters I obtain ready and free circulation of the air through the same.

I claim 1. In stoves or heaters, a casing having two upright branches and a lateral cross connection, one of said branches having a steam inlet near its bottom and the other having a steam outlet, or outlets, near its bottom, said branches and lateral connections being At D the steam will corresponding in position for the purpose of providing suitable air chambers, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of tWo subscribing Witnesses.
